Stepless controllable piston vacuum pump - involves eccentrically mounted worm drive mechanism

摘要

The piston vacuum pump (1) is designed to give stepless control of the delivery flow. The stepless control of the pump action is achieved by a worm drive. The worm drive is mounted eccentrically to the axis of the drive shaft. USE/ADVANTAGE - Vacuum pump for the chemical industry which avoids sealing and cavitation problems.
